NdisFreeSpinLock function (ndis.h)
The NdisFreeSpinLock function releases a spin lock initialized in a preceding call to the NdisAllocateSpinLock function.
Syntax
void NdisFreeSpinLock(
[in] PNDIS_SPIN_LOCK SpinLock
);
Parameters
[in] SpinLock
Pointer to the spin lock to be deinitialized.
Return value
None
Remarks
If the caller of NdisFreeSpinLock needs to use the spin lock again, it must call NdisAllocateSpinLock before passing that spin lock pointer to any of the Ndis..SpinLock or NdisInterlockedXxx functions.
Callers of NdisFreeSpinLock can run at any IRQL. Usually, this function is not called until a driver is unloading.
